Реферат: SEAT MOUNTING FOR OFFICE CHAIRS ABSTRACT Seat mounting, especially for office chairs, having a frame attachable to the lower side of the chair and provided with a pivotal holder for the back-rest and a pivotal holder for the support column of the chair. Secured between said holders and said frame are gas springs counteracting pivotal movement of said holders and, when actuated, permitting said holders to be pivoted. To actuate said gas springs an operating member is pro-vided which is rotatable in opposite directions and also is vertically movable. Upon rotation of said operating member in one direction, one of said gas springs is released to permit pivotal movement of the associated holder. When said operating member is rotated in the opposite direction, the other gas spring is re-leased to permit pivotal movement of the associated holder. When the operating member is raised, both gas springs are released to permit simultaneous pivotal movement of the back-rest and the seat.
